Registros de Dados

Os dados deste recurso de evento de amostragem foram publicados como um Darwin Core Archive (DwC-A), que é o formato padronizado para compartilhamento de dados de biodiversidade como um conjunto de uma ou mais tabelas de dados. A tabela de dados do núcleo contém 459 registros.

Também existem 1 tabelas de dados de extensão. Um registro de extensão fornece informações adicionais sobre um registro do núcleo. O número de registros em cada tabela de dados de extensão é ilustrado abaixo.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

The taxonomic coverage of this dataset spans 1 phylum, 1 class, 1 order, 1 family, 1 genus and 2 species.

Cobertura Temporal

Dados Sobre o Projeto

The dataset contains records of the Cabrera vole (Microtus cabrerae) and other species of the genus Microtus collected in plots along the lower Tua River, included in the Ecological Monitoring Program (2011-2017) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between April 2012 and May 2017 during field visits to 55 known or presumed colonies of the species within a 5-km buffer around the River Tua lower valley. The occurrence of the target taxa was documented through 275 observation events in 165 sampling points distributed among the 54 known or potential colonies. In total, four taxa were identified, at family (1), genus (1) and species (2) levels. Microtus cabrerae was the most abundant species (188 indirect observations/signs of presence), followed by M. lusitanicus (6).

Métodos de Amostragem

Sampling was designed to cover all the potential habitats of the Cabrera vole (fallows, bushes, riverine habitats with low vegetation) in a buffer of 2 km around the lower Tua valley affected by the Foz Tua dam. All areas surveyed during the previous phases of the project (Environmental Impact Assessement and Baseline Studies) were included, and new potential places were added, using aerial photos and other cartographic means, followed by a visit to the area. The search for new potential areas was kept along the duration of the study period. This evaluation furnished a total of 55 areas of known, or presumed, colonies of Microtus cabrera (and other Microtidae). Within these areas, a total of 216 sampling plots was surveyed for signs of the presence of Microtidae (number of tracks, faeces, latrines and heaps of grass clippings) in spring/summer (April-May) and autumn (October-December) of 2012-2017. In each known or potential area surveyed, a detailed description of all the relevant biotopes was performed. This description included (a) the type of biotope, (b) the height of vegetation, (c) the characteristics of the landscape surrounding the demarked areas, namely in relation to the land-use and disturbance. Any changes in these parameters observed between sampling periods were recorded. In the first visit to a colony (or in the subsequent visits, if no faces were found) a feacal sample was collected and sent to laboratory to confirm the presence of the species through molecular analysis. This was performed using the PCR-chain reaction method with specific primers (MiKa1 and MiKa2) that amplify a control region (d loop) fragment of mitochondrial DNA to differentiate samples of Microtus cabrerae droppings from other species of the Arvicolidae family. The sequence detection was performed in the automatic sequencer ABIPRISM® 3730-XL DNA Analyzer from Applied BiosystemsTM, with the above mentioned primers
